Poketto monsutâ - Season 10 Episode 39

As our Heroes continue toward Hearthome City and Dawn's next Pokémon Contest as well as Ash's next Gym battle, they discover a steamboat that travels along the same route they'll be traveling, which gives them an opportunity to do a little pleasure cruising! But when they decide to head into a small town for some supplies before the ship takes off, they leave all their Pokémon alone on the ship, and in their Pokémons' zeal to have a little fun, the ship accidentally starts down the river before our Heroes return – without captain or crew! Luckily, some quick thinking by our Heroes, along with the streamboat Captain's Mantine, allow them to catch up to the boat in the nick of time and save the scared Pokémon from a raging waterfall. And after displaying some amazing courage by Pokémon and trainers alike, the journey to Hearthome City continues.
